Chapter 1. INTRODUCTION
These two units are called G3F-RD3A and G4F-RD2A. The G3F-RD3A is an Pt input module used with the
CPU of GLOFA GM1/2/3 series and MASTER-K1000S series, and the G4F-RD2A is used with the CPU of
GM4 series and K 300S series Hereafter, the two units are called the RTD input module
The RTD input module is a module that converts the temperature data(
°
C) input by the Pt (Pt100 or JPt100)
into a signed 16 bit digital binary data and outputs it.
1.1 Features
1) With direct connection of the RTD input module, the temperature data(
°
C) can be converted into a digital
value to be processed in the PLC.
2) The temperature data(
°
C) input can be processed to one digit after the point as a digital value.
3) One module can be connected to G3F-RD3A 8-point or G4F-RD2A 4-point Pt100 or JPt100.
4) The RTD input module has Pt100, Jpt100 or cable burn-out function at their every channel.
5) The RTD input module detects the out-of-range temperature that is input by Pt100 or JPt100.
